Abstract:The reduction of TiC-containing refiners smelting temperature below 1250°C inevitably leads to the deterioration of their performance. In this work, an improved combustion route is used to prepare Al-5Ti-0.2C master alloy. The separate smelting of Al-10TiC and Al-Ti followed by the intermixing enabled to better kinetic conditions and accelerate the formation of TiC phase. As a result, the smelting temperature was decreased down to 1050°C while the refinement efficacy of the alloy was improved. Comparative analysis of the master alloy microstructure is given with relation to the results of refinement tests. © 2016, The WFO (The World Foundry Organization Ltd). All rights reserved.
